Message: Error in fjj.bd(jjb0) : subscript out of bounds
Available environments had calls:
1: fjj.bd(jjb0)
Enter an environment number, or 0 to exit Selection: 1
Error in get(.obj, envir = dump[[.selection]]) :
recursive default argument reference
The problem is that "debugger" gets an error when trying to
go into the dump. I don't understand what is going on, but
it doesn't have to do with the actual names of the objects --
the same thing happens if all the names are changed.
This is precisely the same on Linux with 1.6.1 and Windows
with 1.6.2.
